To all whom'z'i may concern: I

Be it known that I, FRANK R; IuMnLn,

a citizen of the United States, and resident,

of v an Nuys, Los AngelesCounty, State of California, have invented new and useful Improvements in Gas Brooders, of which the following is a specification. I

This invention relates to chicken brooders and especially to gas 'burnerbrooders. v

An object is to provide a gas" brooder which is of very simple form, and is designed and constructed, to obtain a 'high economy of consumption and'is eflicient in the combustion of the fuel so that no unburned gas escapes to the brooder chamber.

An object is to provide a brooder which is very effective in throwing the heat down toward the chamber floor.

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention here illustrated; it being understood. thatunodifications, variations and adaptations'.may be chicks tend to congregate.

resorted to within the spirit andscope of the inventionas it is here claimed Figure 1 -is a planrparts being broken Figure 2 is a vertical central section.

A serious defect withforms of gas-burn ing chicken brooders is that an objectionable degree of unburnt gas isgiven off because of improper combustion, and another objection isthat too intense a heatbeam is some-- times produced in a localized zonebecauseot an insufli'cient degree of ventilation immediately under the breeder hood wherethe My'present brooder includes a flat,.coni cal top or hood2, of suitable diameter, having on itslower side a central pad. 3 of asbestos against which is secured a center plated. Bolts 5 .pass down through the hood, the asbestos and the plate 4:, which latter is engaged by nuts 6. 5

Below the nuts 6 is a crown or disc 8' adjustable" on the bolts to a desired position below the liner plate- 4 so as to provide an air circulating space 10, which not only provides for flow of air currentsaround and over the crown 8 but also serves to keep flame from the hood2 and-- plate-' 4:, these therefore being protected and allowing use element will not be burnt up by the burner flame. Nuts 9 secure the 'crown' -1n' place.)

The crown is supported directly on top of aburner' head 11 having air holes 12 in its necklS whichlatter is screwed on the upper end of a gas supply pipe li extendingup from the brooder house floor l and having a regulatingvalve 15. i

It will be seen that the burner discharges the gas for combustion close up to the'bottom of. the crown which, sinceit' takes all the burning contact with the flames, may be made of heavy plate or sheet metal and can he removed from timeto time, as necessary.

From the above it will be seen that the crown, not only protects the hood from the f flame but serves as a hot plate to complete combustion of all the gas from the burner,

' and serves, atthe same time, toforin an air circulation space under the hood proper,

such as would not be the case if the burner discharge directly. toward or against the hood. Theheat, instead of being lost bypassing up throughjfthehood, is cast down by the "insulated central part thereof. "lhedevi'ce is of substantial structure and few, parts and these can be packed, sh ipped and stored in nested, knock-down condition.

\Vhat is claimed is: Y v v i 1. A chicken brooder including ahood,

a crown spacediunderthefcenter of the I hood, and a burner on which the crown is supported and .fromwhich gas for combos. tion is dehveredup against the crown.

2. A-chicken brooder including a hood,

eurner'below thehood, and a crown over the burner and-spaced below the hood, where- "by to fornran airspace below the hood and also form a hot plate for combustion" of fuel, and a protective medium lining the central portion of the hood and for reflecting'down heat therefrom and-reducing'loss '01"- heat .byft-ransmission through the hood.

3. A chicken brooder including a hood,

a set of bolts passing through the hood, a

crown plate arranged on the boltsin adjuStable,'spaced position below the hood to ice form an air space therebelow, anda burner directly onwhich the crown is secured to directly receive flame of combustion there from. V .4. A brocder including a hood, a set of bolts passing through the hood, a crown of thinnietal in thejlarge hood element and 'platearranged on the bolts in adjustable,

' thus saving in cost of construction: since this spaced position below the hood .to form an a rspace therebelow,-.and abur'ner -on which the crown is secured; to'directly receive flame of combustion therefrom, and a; heat barrier secured onthe lower face of the hood to protect the same and throw the heat down.

5. A brooder including a hood a set of bolts passing through the hood, a crown plate arranged on the bolts in adjustable, spaced position below the hood to form an air space therebelow, and a burner on which the crown is secured to directly receive flame of combustion therefrom, and a heat barrier secured on the lower face of the hood to protect the same and throw the heat down; the bolts having nuts for securing the crown and the barrier in place.
